EURO QUARTZ CXOXULP OSCILLATORS Ultra-Low Power/Fast Start-Up/High Shock 32.768kHz Actual Size FEATURES Top View Ultra-low current consumption (typically 15µA) Fast start-up (typically 15ms) Tight Tolerance High Shock Resistance Low Ageing Full military testing available Side View OUTLINE & DIMENSIONS DESCRIPTION The CXOXULP 32.768kHz oscillator achieves low power consumption comparable witht a tuning fork design and the fast start up and tight stability obtainable with AT-cut crystal designs. Designed for applications requiring ultra-low current and fast start-upthe part offers stability of ±30ppm to ±100ppm over -55° to +125°C; this being achieved while being able to withstand significantly higher shock than a tuning fork design. SPECIFICATION Frequency Range: 32.7680kHz Supply Voltage: 1.8V to +3.3 Volts ±10% Calibration Tolerance: ±25ppm Frequency Stability over Operating Temperature Range Commercial (0° ~ +70°C): ±10 to ±50ppm Industrial(-40° ~ +85°C): ±20 to ±100ppm Military (-55° ~ +125°C): ±50 to ±100ppm Output Load (CMOS): 15pF Ageing: ±5ppm first year Shock, Survival: Standard: 5000g, 0.3ms, ½ sine HG: 10,000g, 0.3ms, ½ sine Vibration Survival: 20g, 10~2000Hz swept sine Rise and Fall Time: 6ns maximum ENABLE/DISABLE OPTIONS There are two Enable/Disable options available, 'E' and 'N'. The 'E' option stops oscillating when the output is put into the High Z state. the 'N' version does not have Pad 1 connected internally. The table below describes the 'E' Enable/Disable option. Enable (Pad 1 High) Disable (Pad 1 Low) Output Oscillator Current ABSOLUTE MAXIMUM RATINGS Supply Voltage: -0.3V to 5.0V Storage Temperature: -55° t +125°C Maximum Process Temperature: 260°C for 20 seconds Symbol Parameter VOH VOL tstartup tr tf IDD Min.
